Abstract: Abstract Uncertainty is prevalent in the creep resistance of alloys, where at elevated temperature and low pressure, rupture can range across logarithmic decades. In this study, a probabilistic continuum-damage-mechanics (CDM)-based model is derived to capture… read more here.

Abstract: Percolation theory characterizing the robustness of a network has applications ranging from biology, to epidemic spreading, and complex infrastructures. Percolation theory, however, only concerns the average response of a network to random damage of its… read more here.

DOI: 10.1139/cgj-2022-0014
Abstract: To understand the time-dependent fracture behaviour of hard rock in the excavation damage zone (EDZ), a series of stress paths are designed to obtain the same initial damage extent induced by excavation. The influence of… read more here.

DOI: 10.1155/2020/7149148
Abstract: Long-term strength (LTS) of rock materials is important for the long-term stability analysis and the failure prediction of structures in rock engineering. Numerous studies have been carried out on the LTS for various kinds of… read more here.

DOI: 10.3390/ma15165589
Abstract: Existing rock material damage models always ignore the initial damage characteristics of rock materials, and the actual rock materials have initial damage characteristics. To consider the rock’s initial damage characteristics, a series of compression tests… read more here.
